Applications of TIG-welding (Topic: 18014)

TIG-welding is a general purpose welding process for welding of aluminium. Especially at thinner sheet thicknesses (0,5ñ3 mm) the process is qualified.

The process is widely used for welding of pressure vessels, heat exchangers and pipes where tightness is important since the process produces welds with very low pore fractions.

TIG-welding is also beneficial for welds with frequently starts and stops and for short welds due to excellent quality with low porosity.

DC TIG (negative electrode) could in addition also be beneficial for welding thin walled structures and profiles.
